A first glimse into v2.0.114.1 reveals that the Bob Jenkins hash is applied twice now:
1. bobJenkinsHash(info:url) // results in the old checksum seed like used in older toolbar versions
2. generate a 80 byte table from the hash in 1.
3. bobJenkinsHash(80 byte table) // which is the new checksum seed

So all that is necessary is to add the code for converting the first hash into the 80 byte table. I am going to add the assembler snippets in a bit here.

So as I said before, the Bob Jenkins hash is applied twice now:
1. bobJenkinsHash(info:url)
2. the resulting hash (32bit) undergoes a small modification
3. generate a 80 byte table from the modified hash in 1.
4. bobJenkinsHash(80 byte table)

After that, like in previous toolbar versions, you convert eax to unsigned integer and prepand CH=6.

The remaining step is to transcode the assembler snippets into high-level again.
